1. Feature Of The Week

    In this paper, we report what we believe is a novel technique to overcome the depth-of-focus (DOF) limitation in optical coherence tomography (OCT). Using confocal optics on a sample arm, we scanned the illumination beam across the under-filled objective lens pupil plane by steering the beam at the pinhole using a microcylindrical lens. The detected interferometric signals from multiple distinctive apertures were digitally refocused, which is analogous to synthetic aperture radar (SAR). Using numerical simulations and imaging experiments, we verified that this technique can maintain a diffraction-limited transverse resolution along a DOF that is ∼10∼10 times larger than the confocal parameter. The ability to extend the DOF without signal loss and sidelobe artifacts may ultimately overcome the DOF limitation in high-resolution OCT.

      Compact Imaging, Inc. (CI) today announced that SRI International has selected CI’s non-invasive depth scanning sensor, MRO™, as a critical component in the development of “dynamic biometrics” for improved detection of attempts to evade or deceive biometric security systems, such as fingerprint scanners. The development is being performed under a multi-year contract awarded to SRI as part of IARPA’s (Intelligence Advanced Research Projects Activity, National Intelligence Directorate) Odin Program. The goal of the Odin Program is to develop advanced technologies to detect “presentation attacks,” as attempts to deceive biometric security systems are often called.

      16  MHz wavelength-swept and wavelength-stepped laser architectures based on stretched-pulse active mode locking with a single continuously chirped fiber Bragg grating

      We demonstrate a novel high-speed and broadband laser architecture based on stretched pulse active mode locking that provides a wavelength-swept and wavelength-stepped output. The laser utilizes a single intracavity 8.3 meter chirped fiber Bragg grating to generate positive and negative dispersion, and can be operated with or without an intracavity fixed Fabry–Perot etalon to generate wavelength-swept and wavelength-stepped (frequency comb) outputs, respectively. Using a four-path delay line at the output, we achieved 16.3 MHz repetition rates and a 62 nm lasing bandwidth centered at 1550 nm. Single-sided double-pass coherence lengths of 1.25 mm for the wavelength-swept ...

      Investigating the influence of organic matter composition on biofilm volumes in reverse osmosis using optical coherence tomography

      Biofouling, a critical issue in membrane filtration, is influenced by several factors such as membrane characteristics and feed water quality. The organic matter (OM) composition is known to significantly influence biofilm formation, but few studies on this subject have been reported. Optical coherence tomography (OCT) allows direct monitoring of biofilm development on the membrane surface without the need for membrane autopsy. The purposes of the present study are 1) to quantify biofouling formation on a membrane surface using OCT; 2) to monitor the temporal variation of OM composition during membrane formation; and 3) to investigate the variation of OM composition ...

This randomized controlled single-blind cross-over clinical study aimed to evaluate the use of SS-OCT for detecting optical changes in the enamel of 30 healthy volunteers subjected to orange juice rinsing (erosive challenge) in comparison to mineral water rinsing (control), according to wiped and non-wiped enamel surface states.

      Optical coherence tomography (OCT) has recently been demonstrated to measure the film coating thickness of pharmaceutical tablets and pellets directly. The results enable the analysis of inter- and intra-tablet coating variability at an off-line and in-line setting. To date, only a few coating formulations have been tried and there is very little information on the applicability of OCT to other coatings. As it is well documented that optical methods including OCT are prone to scattering leading to limited penetration, some pharmaceutical coatings may not be measurable altogether. This study presents OCT measurements of 22 different common coatings for the assessment ...

      Speckle-modulating optical coherence tomography in living mice and humans

      Optical coherence tomography (OCT) is a powerful biomedical imaging technology that relies on the coherent detection of backscattered light to image tissue morphology in vivo . As a consequence, OCT is susceptible to coherent noise (speckle noise), which imposes significant limitations on its diagnostic capabilities. Here we show speckle-modulating OCT (SM-OCT), a method based purely on light manipulation that virtually eliminates speckle noise originating from a sample. SM-OCT accomplishes this by creating and averaging an unlimited number of scans with uncorrelated speckle patterns without compromising spatial resolution. Using SM-OCT, we reveal small structures in the tissues of living animals, such as ...

A similar condition as a result of nontraumatic cause is referred to as “Purtscher-like retinopathy.” The diagnosis is primarily clinical and includes unilateral or bilateral sudden vision loss with fundus features, including cotton wool spots, intraretinal hemorrhage, and pathognomonic Purtscher flecken (retinal whitening with periarteriolar sparing). These features result from the occlusion of precapillary arteriole possibly from fat embolus or leukoaggregates. 2 Fluorescein angiogram may show blocked choroidal fluorescence because of retinal whitening ...

      Automatic detection and recognition of multiple macular lesions in retinal optical coherence tomography images with multi-instance multilabel learning

      Detection and recognition of macular lesions in optical coherence tomography (OCT) are very important for retinal diseases diagnosis and treatment. As one kind of retinal disease (e.g., diabetic retinopathy) may contain multiple lesions (e.g., edema, exudates, and microaneurysms) and eye patients may suffer from multiple retinal diseases, multiple lesions often coexist within one retinal image. Therefore, one single-lesion-based detector may not support the diagnosis of clinical eye diseases. To address this issue, we propose a multi-instance multilabel-based lesions recognition (MIML-LR) method for the simultaneous detection and recognition of multiple lesions. The proposed MIML-LR method consists of the following ...

While we have been actively advancing our lesion assessment technology for the last two years, we are very pleased to see that the significant Series B investment will give MedLumics the means to complete our best-in-class product, conduct a series of international clinical trials to prove its safety and efficacy, and market it to specialist centers. As the company advances and grows into new areas, we will now expand and develop the team internationally.

    5. Our OCT Angiography congresses is a major force in promoting the transition from FA to OCTA by educating the ophthalmologists .

    6. The development of OCT in the early 1990s greatly benefited from components and methods used in fiber-optical communications...And still, 25 years later, advances in the optical communications industry continue to greatly benefit OCT.

    7. Research by our group at MIT and our collaborators at Praevium Research and Thorlabs indicated that the coherence length of the VCSEL source was orders of magnitude longer than other swept laser technologies suitable for OCT, which suggested the possibility of long-range OCT imaging.

    8. Our study demonstrates world-record results in cubic meter volume imaging, with at least an order of magnitude larger depth range and volume compared to previous demonstrations of three-dimensional OCT...These results provide a proof-of-principle demonstration for using OCT in this new regime...Long-range OCT is a new range of operation that requires extremely high performance light sources, integrated optical receivers and signal processing.
